How did scientists come up with the name Rh factor?
The antigen was first discovered in the blood of Rhesus monkeys.
Where did the rh antigen get it name?
The Rh antigen got its name from the Rhesus monkey, in which it was first discovered in the early 1940s. Researchers were studying the blood of these monkeys and identified the antigen that could cause immune reactions. The "Rh" stands for "Rhesus," and it has since become a critical component in blood typing and transfusions in humans.
What is Australian antigen test?
Australia antigen,1 an envelope antigen known as hepatitis B surface antigen (HBsAg), found in acute or chronic hepatitis B.2 a serologic marker on the surface of the hepatitis B virus.It is commonly referred to as the Australia Antigen. This is because it was first isolated by the American research physician and Nobel Prize winner Baruch S. Blumberg in the serum of an Australian Aboriginal person.It was discovered to be part of the virus that caused serum hepatitis by virologist Alfred Prince in 1968.Heptavax, a "first-generation" hepatitis B vaccine in the 1980s, was made from HBsAg extracted from the blood plasma of hepatitis patients. Current vaccines are made from recombinantHBsAg grown in yeast.
How did the discovery of the rhesus affect society?
Rh factor is also called "Rhesus factor" because it was first discovered in the blood.

Why does a patient's body accept the blood by transfusion despite the fact that the immune system tends to reject foreign objects?
To learn the answer of the above question first we have to know about the blood characteristics.There are four major types of blood A, B, AB, and 0. The blood types are determined by proteins called antigens. This antigen is found on the surface of the Red Blood Cell (RBC). Basically there are two antigens, A and B. If you have the A antigen on the RBC, then you have type A blood. When B antigen is present, you have type B blood. When both A and B antigens are present, you have type AB blood. When either are present, you have type O blood. When an antigen is resent on the RBC, then the opposite antibody is present in the plasma. For instance, type A blood has anti-type-B antibodies. Type B blood has anti-type-A antibodies. Type AB blood has no antibodies in the plasma, and type O blood has both anti-type-A and anti-type-B antibodies in the plasma. These antibodies are not present at birth but are formed spontaneously during infancy and last throughout life. In addition to the ABO blood group system, there is an Rh blood group system. There are many Rh antigens that can be present on the surface of the RBC. The D antigen is the most common Rh antigen. If the D antigen is present, then that blood is Rh+. If the D antigen is missing, then the blood is Rh-. Blood is transfused to a patient after determining the blood group and matching the characteristics of both. In such case the immune system accepts the foreign object.
How was the rh factor named?
The "Rh" factor was named after the Rhesus monkey, in which the blood protein was first identified. The discovery of this protein in humans was made in the late 1930s by Landsteiner and Wiener, who named it "Rh" after the initial of the Rhesus monkey.
Who discovered the first river?
because you smell
What do the blood type letters mean?
The letters of the blood types are assigned by the number of antigens in the person's blood. A and B are used because they are the first two letters of the alphabet. O is used to signify zero, as in zero antigens.
What is the first step of the immune response?
antigen
Why can a person with rh- blood not receive rh plus blood?
The person with Rh- blood will begin to make antibodies against Rh+ upon exposure. This may not occur with the first transfusion - but it is still not recommended to give an Rh- person Rh+ blood.
What was the first disease discovered?
It is unknown...but a guess is that some bacterial disease was discovered first because bacteria is an ancient organism....
